Thank you EA_Aljo For replying to this thread.
The evidence is all in the game history. To further explain what the player in question has done:
He played on three other clubs to boost their RP then had his friends match his club(Beyond Limits) with those clubs and DNF against his club that is currently ranking #1 in the elite 3v3 playoffs.
This is extremely childish behavior that has for now ruined the 3v3 playoffs for everyone else competing on the leaderboard.
IMO the clubs and the players involved should already have been banned and removed from the leaderboards. However i truly hope that EA takes this seriously and will take action against this blatant cheating.
